ETHNOPHARMACOLOGICAL RELEVANCE Urban Ethnoveterinary should be further explored because of its value as it resists conventional medical care. In addition, the comparison between the resources used by Ethnoveterinary and Ethnopharmacology should be investigated in depth, increasing the availability of new bioactive potential in human and veterinary(More)
BACKGROUND This study was aimed at assessing the psychometric qualities of the abbreviated versions of the Alcohol Use Disorders Identification Test (AUDIT-3, AUDIT-4, AUDIT-C, AUDIT-PC, AUDIT-QF, FAST, and Five-Shot) and at comparing them to the 10-item AUDIT and the CAGE in 2 samples of Brazilian adults.

—This paper presents a comparison between the k-Nearest Neighbors, with an especial focus on the 1-Nearest Neighbor, and the Optimum-Path Forest supervised classifiers. The first was developed in the 1960s, while the second was recently proposed in the 2000s. Although, they were developed around 40 years apart, we can find many similarities between them,(More)

The Max-Tree is an efficient data structure that represents all connected components resulting from all possible image upper threshold values. Usually, most of its nodes represent irrelevant extrema, i.e. noise, or small variations of a connected component. This paper proposes the Maximal Max-Tree Simplification (MMS) filter with a normalized threshold(More)
